I'm not sure the mailing list software appreciated me attaching a file, so
I've pasted the MIB in below:
MIB-TEST DEFINITIONS ::= BEGIN
IMPORTS Integer32, enterprises FROM SNMPv2-SMI
OBJECT-TYPE FROM RFC-1212;
mycompany OBJECT IDENTIFIER ::= { enterprises 999999 }
component OBJECT IDENTIFIER ::= { mycompany 1 }
functionalarea OBJECT IDENTIFIER ::= { component 3 }
connectedServiceQueueSizes OBJECT-TYPE
SYNTAX SEQUENCE OF ConnectedServiceQueueSizeEntry
MAX-ACCESS not-accessible
STATUS current
::= { functionalarea 1 }
connectedServiceQueueSizeEntry OBJECT-TYPE
SYNTAX ConnectedServiceQueueSizeEntry
MAX-ACCESS not-accessible
STATUS current
INDEX { serviceID }
::= { connectedServiceQueueSizes 1 }
ConnectedServiceQueueSizeEntry ::= SEQUENCE {
serviceID Integer32,
queueSize Integer32
}
serviceID OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS not-accessible
STATUS current
::= { connectedServiceQueueSizeEntry 1 }
queueSize OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
::= { connectedServiceQueueSizeEntry 2 }
END

Hi Frank,
Thanks for the tip - I've downloaded MIB Explorer, but unfortunately when
using the attached MIB file I'm encountering the following problems:
1) When importing the MIB, I'm encountering 4 instances of the following
syntax error: "Error 1000: Encountered "MAX-ACCESS" Was expecting:
"ACCESS"...". Can you see what the problem is? My MIB newbie eyes can't
see any difference between my MIB and similar table definitions in other MIB
files.
2) If I go ahead and choose to import the MIB with the most lenient syntax
checks, I get the following exception when attempting to browse down through
the tree to the node for the defined table (which I concede may well be due
to the flawed MIB!):
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Apologies if this isn't the correct forum to discuss MIB Explorer issues,
but any help would be much appreciated!
Thanks
Paul

Hi Paul,
You have taken my MIB Explorer Pro into
account yet?
An evaluation version is available from
http://www.mibexplorer.com
The upcoming 3.0 release will get a DB
interface to put monitored values directly into a SQL database (DB2, Oracle,
MySQL, etc.).
I am not sure if that is what you are
looking?
Best regards,
Frank
